A profile view from the normalized point cloud in Superior National Forest, notice the flattened ground surface.  Points are colored by elevation.

Excerpt of satellite image showing landslide impacts to roads, agriculture, and a reservoir in the Lares Municipality. Points identify the approximate location of roads visibly impacted by landslides. Image filename contains approximate latitude and longitude of this impact location.

(Top) Methane plumes at the Norfolk Canyon seeps (~1600 meters or 5250 feet) were detected using the EK60 sonar. The water column plumes are shown above the sub-seafloor structure as imaged by high-resolution multichannel seismic data acquired by the USGS and processed by J. Kluesner.

This photo was taken during USGS unmanned aerial systems (drone) pilot training. Two training sessions were held - one in February-March 2017 in Santa Cruz, California and the second in April 2017 in Gainesville, Florida.

Estimated and measured ocean depths (bathymetry) from Madeira Beach, Florida. Each panel shows same geographic area. m = meters. Left: Snapshot transformed from original oblique camera view to overhead “map” view. Middle: Bathymetry estimated by applying cBathy algorithm to July 2017 video imagery. Right: Bathymetry measured with sonar in February 2017.

An interdisciplinary USGS team is conducting research and developing tools to identify suitable coastal habitats for species of concern, such as the piping plover (Charadrius melodus), under a variety of sea-level rise scenarios.

The R/V Muddy Waters lends itself to be a versatile survey launch and assistance vessel for the deployment and retrieval of inshore moorings and scientific sensor platforms. The boat can easily be towed to location by a full sized pickup truck and is easily launched and retrieved for fast mobilization after storm events or other rapid response surveys.
